These are expensive but after a month of use I did see a noticeable improvement to the colour of my teeth. Also some teeth whitening kits have left my teeth sensitive in past and this product did not. This product has become a part of my regular beauty routine.

I recommend it to all.i use it every day more than 6 years.i love it it gives me feeling confident.really good and effective

I tried Crest Whitestrips years ago. They whitened my teeth but were awkward to use as the strips didn't adhere to my teeth very well. That has changed! They now stick very well, so much so that they don't slip or slide at all. They make such a difference in how white my teeth are. You can even notice the difference after the first use.

They do make my teeth sensitive so while I use the strips I use a toothpaste for sensitivity. It is well worth it for how white they make my teeth!

This product really works and whitens your teeth. I use it all the time. Yes it's a little pricey but well worth it when you see the results . My friends cannot believe the difference and are now using it. For the little time it takes to apply I promise you will love it to

I have used these for keep my teeth clean and white between my dentist appointments they work beautifully. My teeth look great and my mouth feels clean.

I have tried professional whitening system from my dentist and recently I try Crest Whitestrips advance seal. I actually prefer Crest Whitestrips advance seal, it's easier to use with same great result!

By far my favorite whitening product! Crest whitestrips are so simple and easy to use. My teeth have always had a yellow tint to them, and since I started using crest whitestrips, my teeth have never been so white. I am constantly getting compliments on how beautiful and white they are! After asking my dentist to have my teeth professionally whitened, he said to use Crest whitestrips. They are more effective than any whitening process.

Works grat. Got amazing reviews for my smile!

My absolute favourite product....my teeth get so many compliments and I feel so confident,

I purchased crest white strips about 2 months before my wedding , my husband and i had used them 3 times a week before the wedding ,within 2 weeks we had already noticed a difference ,great product will purchase again!!
